    Has anyone done this with any success? What is the absolute EASIEST way to repair any cracks in these things?? I've got about 4 sets here and they all have a crack or a chip in them.

    If I use the figerglass kit, do I need the mesh? If so, how would I apply it to such a small area??

    Is there something in a tube I can buy and just apply and then sand down once it dries?? Mixing this stuff up is kind of a pain in the butt....

    ANY help is appreciated....thanks! :TU:

    try some 2 part epoxy. there are different types so read the label carefully.you probably want one that sets pretty hard so it can be sanded and drilled.

    Brett I got your parts today. It looks like i'm going to be doing repair throughout the whole piece, so i'll end up painting the whole thing. All in all, everything will be nice once i'm done. I'll refill your cup holder screw holes with some 2 part urethane epoxy so you can put the cups back on.

    Read the directions on the fiberglass resin on how to mix the stuff up. I prefer buying the mesh over the cloth and then pull it apart and repair the cracks that way since it isn't a big job. Good Luck

    GStage1 Always looking for parts!

    Use the epoxy set-up. I think it was called Dev-con or similar. Kind of a black and gray mixture. Works extremely well and states on the packaging that you can drill it for sheet metal screws. You will need to "v" your cracks on the flat areas to provide fresh surfaces for proper adhesion. For the round "bosses" where the screws go, you can use wax paper wrapped with duct tape or masking tape to hold form while you pour in the epoxy mix.

    Jarrod,

    Sounds good! I'm looking forward to seeing how it comes out...I didn't realize that thing was in such bad shape....

    Have you sent out that sensor yet? If not, just send it back with the rest of the stuff....thanks!!

    George,

    I actually used the Devcon Liquid Aluminum today to fill up the "bosses", per and old GS X-tra article....I wasn't sure if I could use it for the cracks...

    Would Permatex "Cold Weld" work as well??

    When you say "v" the cracks, does that mean spread them apart a little? :Do No:

    (I'm a novice to all the bodywork lingo, in case no one noticed :Dou: )

    Thanks!

    Here's a pic of the "bosses" filled with Devcon Liquid Aluminum..

    I think me have a problem with the sensor you should have had that by now. It went out quite sometime ago. Keep me posted on that. I might be able to put another one together if it doesn't show, but if it does you can either pay for the extra one or send it back to me. I'll let you know when I have these parts done,and hopefully the sensor gets there before i'm done with this stuff so i'm not out parts. Talk to ya' soon.

    Use a Dremel tool or a file over the crack to make a "trench" for the epoxy to fill

    POR 15 makes a putty that is used for filling pits etc. It mixes like play-doh and once dry is very hard yet can easily be sanded and tapped etc. Its also very strong. I was thinking next scoop I repair will use this stuff, I have found using epoxy to fill the stripped out holes etc usually just results in the epoxy pulling back out later on.

    This stuff is very nice to work, yet very hard and very light. Just a thought.

    later

    Tim is right, I have used POR putty to repair my 71 grille. Stuff is rock solid.
